    What kind of system do you have with a boiler/duct work? What do you mean by the sight glass is melted? Turn that boiler off and post some pictures of the boiler, the sight glass and the piping around the boiler. You need to get a professional in there to look at that boiler before you start it back up. Do you see any water in the sight glass? If it's really melted/broken did water run out onto the floor?
    Where are you located?

    Glass will only melt in direct flame with no cooling. So -- it must be something else that you are referring to. Pictures?

    Possibly an inspection window for a forced air furnace??

    Makes perfect sense! I'm fixated on steam. :)

    thanks for all your comments. sorry i was not very clear. it is a forced hot air gas furnace, the glass is or was sight glass.
    I had a havc tech come look at the furnace, he said the heat chamber was cracked and the one fan had stopped working, I had it replaced with another furnace. Thank you all again
